TO ALL IVI-IOM IT MAY CONCERN:

Be it known that I, GEORGE I-Ionrnnr, of -Whitley Lodge, in the pui-ish of Halesowcn, in the county of Worcester, England, have invented n. new and iminovedV -Mode of Preparing Iron or Steel Rods 01' Bars to Form Chain Links; and I do hereby declare that the following is a full :ind exact description thereof, which will enable others sl'iilled in the art to make :ind use the saine, reference being` had to the accompanying drawings, forming part of lthis specilication, in-.which Figure 1 is a front elevation.

Figure 2 is a top view.

Figure 3 is an end elevation; and

Figure 4. is a section onv the linc a; y.

The letters ofreferenoeindioate in all the views similar parts.

machine, as I prefer. to construct it, is made with a hed, A, having two slides, as shown more distinctly on {ign/I by a a, and two feed-screws, S S. Attached to one end of this bed is the head-stock B, which carries the main spindle C, with the loose geur-wheel c', and underneath it the driving-shaft D, iig. 1, with pinion d and mitre-wheel c und driving cone-pulleys d d. `An idler mitre-wheel,f, is placed under the head-stock, and imparts motion to the loose mitre-wheel y. Also, underneath the head-stock, and in line with the driving-Wheel shaft D, is placed the feed-screw S, upon the end oi' which the loose mitre-wheel g can revolve. The clutch E, sliding on feathers intho end of the screw S, can be shifted by the'clutch-lever 7i from the clutch-teeth upon the wheels e and g, and a right or loft-hand motion can be thus imparted to the screw S. On the back side of `the head-stock is placed the gear-wheel z', which communicates motion to the system of change-wheels z" 2', driving the screw S, so os to give any required number of revolutions as compared with the revolutions of the spindle. The clutch F, (operated by the handle j,) sliding on feathers on Vthe main spindle C, stops and starts the spindle and the screw S. Upon the face of the spindle C is placed the chuck G, which carries one ,end of the mandrel H, which mandrel is formed with such .section as will give the shape desired for the interior of the unwelded link. The mandrel passes through the stripping-collar G and I, the steady-rest collar I', and a bearing at the other end', I. The stripping-collant I runs in the'carriage J, which is traversed up and down the hed A on the slide a, by' the screw' S and nut e', (sce g. 4,) thc rod 7L, with the pins 't 7L, which will be struck by the head J as it approaches the ond of its motion, preventingy any over-running of the screw. The dog,r /c is inserted in the face of' the stripping-collar I. The steady-rcst collar runs'in the head K, which is carried upon and moves with the carriage M, andsustains the nrndrel ucar thcplace upon which the bar or' rod is being coiled, (the steady-rest collar is not needed for the largo coils,) and the bearing I is in the moving-head L, which rests upon the slide a, but is not driven by the' screw S. These last two-supports swin,r away to allow the coil to be stripped off thelmandrel. The carriage Irl traverses upon the bed A on the slide a, being driven down the bed, awa-y fromthehead, by the screw S and the opening-nut N. This nut is opened and closed hy the cams n and handle n, by means of which it cnn be engaged with or disengaged from the screw. The worm-wheel O, with its cranknandle e, enables Ythe bed M to be returned up the bed A hy hand. The sliding-carriage M carries the head P, into which is fixed the levery), by means of which a grooved roller made to bear upon the rod or bar to be coiled, so ns to distribute it uniformly upon the mandrel.

The mode of operating this machine is ns follows: The stripping-collar I is placed near the chuck G, and the head-pin is placed in such a position that the bar or red passing through I? will pass under the dog 7c, between it and the mandrel Il. There is thon taken a. bnr or rod, while yet at the proper heat, after having been rolled, (I prefer this to reheating7 although reheating will answer.) the ond of which is inserted under the dog 7c, .and upon starting the spindle (by the lever j) the carriage M travels down the hed Asimultaneously with the rotation of the mandrel Il, until the entire length ci rod. is coiled upon the mandrel II. Permitting the machine to remain in motion until the steady-rest collar If passes thc end of the mandrel II, removing the bearing I as it passes, and then stopping and morin` If and I aside, the screw S is then placed in motion, (by the lever 71,) und the strippingcollar I moved down the mandrel, shoving the coil before it. For some purposes the rods or hars may he coiled cold. Ail-.er I have thus made o. coil, I proceed to cut, shear, or sew up the same in such a. Way as to form the proper scarf or ln-p for welding when onol or [pore convolutions of such coil are compressed together.

Who/t I claim as my invent-ion, and desire to secure by Letters Patent, is- 'lhe rotating mandrel H, in oombnzltion with the carriages M and J, or any construction, substantially the same, arranged and operated substantially as described for the purpose 0f laying and stripping the coil cf rod or bm'.
